Could you change the Layout header slot from a child component?

Ok so this is something I have been thinking these past few days. Could you update a slot of the parent from inside a child?
In my case I use the Quasar Layout component (as you should) and in one of my routes, I need to change the whole template of the slot. My route is something like this:

Uh, there is so much to explain here. I’ll try to be short and to the point. Use a store or vuex to manage the state of the layout. Then, when you visit a certain route simply change the state. This way the layout will know what to display in the header.
